Arduino开发板:作为整个项目的控制核心,可以选择Arduino Uno、Nano等常见的型号。 显示屏:一个小型的LCD或OLED显示屏,用于显示游戏画面。例如,可以使用1.8英寸的TFTLCD显示屏。 按钮:用于游戏的操作,至少需要准备4个按钮,分别对应上、下、左、右方向键,以及A、B等操作按钮。 蜂鸣器:用于游戏中的音效提示,增加游戏的...
我用arduino使用i2c接口的液晶屏是出现了按键一按,程序就卡在显示那个地方了。下面我详细介绍下。 首先,你得安装相关库,如下图所示: 然后,可以在示例里面选择相关的例程,如下: 下面我说一下我遇到的问题。我同时用到了按键和显示。显示我用的是lcd.print()函数,但是我发现,这个......
// include the library code:#include <LiquidCrystal.h>// initialize the library with the numbers of the interface pinsLiquidCrystal lcd(13, 12, 11, 10, 9, 8);int pin = 2; //定义引脚为D2unsigned long duration=0; //定义duration变量为无符号长整数型变量int i = 0;void setup(){pinMode...
Here is a simpleArduino projectthat focuses onadjusting the brightness of an LCDscreen whenever there isn’t sufficient light in a room. The Arduino reads the surrounding light intensity usingan LDR sensor. Theroom temperature and humidityrange will also be displayed on the LCD. The entire hardwa...
This is simple just connect the usb which you use to program the arduino into a free port on the Raspberry PI Step 4: The Code & How It Works As you can see in the images and the code I added two more wires from the arduino to the LCD these basically control the LCD contrast inst...
So finally, this whole thing is a simple way to generate sine wave shaped signals using Arduino and square wave pulses of changing width. In the next post I'll explain how to use the above Arduino based SPWM generator tomake a pure sinewave inverter circuit...keep reading! The...
properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn't start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is thesolut...
TFT LCD Support: Pre-configured for popular TFT LCD displays. LittleFS + Arduino LVGL Driver: File system driver setup for LVGL (see src/littlefs_fs_drv.cpp). Simple Keypad Input Device: 4-button keypad input device setup (see include/keypad_indev.h and src/keypad_indev.cpp).Getting...

I am trying to use PWM to vary the backlight intensity of an LCD on both projects, It works perfectly on one board, very badly on the other. I finally traced it down to a conflict between Servo.h and the ledc both using the same hardware timer (Servo wins out, and the PWM can ...
